Given numbers are 971,986,720,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 971,986,720,923 is 318126865680.
Find LCM of 971,986,720,923 with Prime Factorization
2 | 971, 986, 720, 923 |
971, 493, 360, 923 |
Multiply the prime numbers at the bottom and the left side.
2 x 971 x 493 x 360 x 923 = 318126865680
Therefore, the lowest common multiple of 971,986,720,923 is 318126865680.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
971 x 986 x 720 x 923 = 636253731360
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
971 : 1, 971
986 : 1, 2, 17, 29, 34, 58, 493, 986
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,986,720,923, is 1.
Now, the common factors can be found like this.
971:971
986:2x 17x 29
720:2x 2x 2x 2x 3x 3x 5
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 636253731360/(1x2)
LCM = 636253731360/2
LCM = 318126865680
Thus, we can understand that the LCM of 971,986,720,923 is 318126865680.
